Hi Russell,
By reading the code of show_mem(), I found that there is an assumption
that the page structs must be continuous for each bank:
for_each_bank (i, mi) {
...
page = pfn_to_page(pfn1);
end = pfn_to_page(pfn2 - 1) + 1;
After a5f4f52e82114e85aa1a066bd1a450acc19a464d

3: use kmalloc i

This patch adds the core volatile range shrinking logic needed to
allow volatile range purging to function on swapless systems
because current VM doesn't age anonymous pages in case of swapless
system.
Hook shrinking volatile pages logic into VM's reclaim path directly,
where is shrink_list which
If VM discards volatile page of shmem/tmpfs, it should remove
exceptional swap entry from radix tree as well as page itself.
For it, this patch introduces shmem_purge_page and free_swap_and_
cache_locked which is needed because I don't want to add more
overhead in hot path(ex, zap_pte).
A later p
struct vrange has a purged field which is just flag to express
the range was purged or not so what we need is just a bit.
It means it's too bloated.
This patch changes the name with hint so upcoming patch will use
other extra bitfield for other purpose.

This patch adds purging logic of volatile pages into direct

they could be discarded rather than swapping out.

Now, we scan and discard volatile pages per vrange size but vrange

Another problem is we always start fr
By vrange(2) semantic, a user should see SIGBUS if they try to

This allows for optimistic traversal of volatile pages, without
having to mark them non-volatile first and the SIGBUS allows

Hey all,
Happy New Year!
I know it's bad timing to send this unfamiliar large patchset for
review but hope there are some guys with freshed-brain in new year
all over the world. :)
And most important thing is that before I dive into lots of testing,
I'd like to make an agreement on design issues
This patch allocates vroot dynamically when vrange syscall is called
so if anybody doesn't call vrange syscall, we don't waste memory space
occupied by vroot.
The vroot is allocated by SLAB_DESTROY_BY_RCU, thus because we can't
guarantee vroot's validity when we are about to access vroot of

From: John Stultz
At lsf-mm, the issue was brought up that there is a precedence with
interfaces like mlock, such that new mappings in a pre-existing range
do no inherit the mlock state.
This is mostly because mlock only modifies the existing vmas, and so
any new mmaps create new vmas, which won
This patch adds vroot on mm_struct so process can set volatile
ranges on anonymous memory.
This is somewhat wasteful, as it increases the mm struct even
if the process doesn't use vrange syscall. So a later patch
will provide dynamically allocated vroots.
One of note on this patch is vrange_fork.

1. Start with a good kernel. In this case, I suppose 3.8.2 is the
right place to begin.

When a CPU is hot removed we'll cancel all the delayed work items via

it should adjust the delay for all other CPUs that the policy is

work

When the skb is xmit by the function bond_slave_override(),
it will have duplicate judgement for slave state, and I think it
will consumes a little performance, maybe it is negligible,
so I simplify the function and remove the unwanted judgement.

This serious of patches will slight optimize the mac address compare
and xmit path for bonding, also make some cleanups.
Julia was using ether_addr_equal_64bits to instead of ether_addr_equal,
it is really a hard work and she may did not make patch for bonding yet,
so I have do it in this patchset
The net_device.dev_addr have more than 2 bytes of additional data after
the mac addr, so it is safe to use the ether_addr_equal_64bits().

Use possibly more efficient ether_addr_equal_64bits
to instead of memcmp.
Modify the MAC_ADDR_COMPARE to MAC_ADDR_EQUAL, this looks more
appropriate.
The comments for the bond 3ad is too old, cleanup some errors
and warming.

I'm sure the operand slave and bond for the function will not
be NULL, so the check for the bond will not make any sense, so
remove the judgement, and the return value was useless here,
remove the unwanted return value.

The return value for bond_dev_queue_xmit() will not be used anymore,
so remove the return value.

The bond_dev_queue_xmit() will always return 0, and as a fast path,
it is inappropriate to check the res value when xmit every package,
so remove the res check and avoid once judgement for xmit.

The bond_alb_xmit will check the return value for
bond_dev_queue_xmit() every time, but the bond_dev_queue_xmit()
is always return 0, it is no need to check the value every time,
so remove the unneed judgement for the xmit path.

New version of the PCU firmware supports two new commands:
- IMS_PCU_CMD_OFN_SET_CONFIG which allows to write data to the
registers of one finger navigation(OFN) chip present on the device
- IMS_PCU_CMD_OFN_GET_CONFIG which allows to read data form the
registers of said chip.

We have things called "libraries", see the mailing list.
